Abstract

In prodn. of powdery copolymers of maleic anhydride with methyl vinyl ether in a molar ratio of 1:1 having a specific viscosity of 2-5 by copolymerisation of maleic anhydride and methyl vinyl ether under pressure in the presence of polymerisation initiators which undergo radical decomposition the copolymerisation of the maleic anhydride is carried out in 3-20 (pref. 6-15) molar proportions of methyl vinyl ether and the radical polymerisation initiator is used in an amount of 0.001-1 (pref. 0.01-0.5) wt%, based on the amount of maleic anhydride.
